TCC0201X7R471K500ZT 贴片多层陶瓷电容(MLCC)产品概述

一、产品核心身份识别

TCC0201X7R471K500ZT是三环(CCTC) 推出的一款小型化贴片多层陶瓷电容(MLCC),型号命名遵循行业通用规则:

  • 前缀「TCC」为三环品牌标识;
  • 「0201」对应英制封装尺寸(公制0.6mm×0.3mm);
  • 「X7R」为温度系数分类;
  • 「471」表示容值(47×10¹=470pF);
  • 「K」为精度等级(±10%);
  • 「500」代表额定直流电压(50V);
  • 尾缀「ZT」为三环内部系列区分(含端电极设计优化)。

该产品定位为平衡性能与成本的通用型MLCC,覆盖消费电子、工业控制等多场景需求。

二、关键参数解析

1. 电气性能核心指标

  • 容值与精度:470pF(471)±10%(K档),满足大多数电路对容值偏差的容忍度,无需高精度的场景下成本更具优势;
  • 额定电压:50V直流,实际工作电压建议控制在40V以内(电压降额80%),避免长期过压导致的老化失效;
  • 温度系数:X7R,温度范围-55℃~+125℃,容值变化率≤±15%——属于中温稳定型介质,兼顾宽温适应性与容值密度(介电常数≈1500-2500);
  • 绝缘电阻:≥10¹⁰Ω(25℃,10V直流),漏电流极低,适合电源滤波、信号耦合等对绝缘要求高的场景。

2. 物理与封装特性

  • 封装尺寸:0201(0.6mm×0.3mm×0.3mm),是目前小型化MLCC的主流封装之一,适配高密度PCB设计(如智能手机、可穿戴设备);
  • 端电极结构:采用「银层+镍层+无铅锡层」三层设计,兼容回流焊、波峰焊工艺,焊接可靠性达行业标准(焊接后无脱落、开裂风险);
  • 环保合规:符合RoHS 2.0、REACH等环保指令,无铅无卤,满足出口及高端产品要求。

三、封装与结构优势

TCC0201X7R471K500ZT采用多层堆叠陶瓷结构:内部由陶瓷介质层与钯银内电极交替堆叠,经高温烧结形成一体化结构——相比单层陶瓷电容,容值密度提升3-5倍,同时保持低损耗特性。

其端电极设计针对小型化封装优化:外层锡层采用低熔点合金,降低回流焊温度对电容的热冲击;镍层作为阻挡层,避免锡层向陶瓷介质扩散,提升长期可靠性。

四、典型应用场景

1. 消费电子领域

  • 智能手机/平板电脑:音频电路耦合(如耳机接口滤波)、射频前端去耦(470pF适配中低频信号滤波);
  • 可穿戴设备:智能手环/手表的电源滤波(50V电压覆盖低功耗电路需求)、传感器信号降噪。

2. 工业控制领域

  • 小型PLC模块:数字输入/输出电路去耦,X7R的宽温特性适配工业环境(-40℃~85℃);
  • 传感器节点:温度传感器、压力传感器的信号滤波,避免电磁干扰。

3. 通信设备

  • 路由器/交换机:电源模块滤波(470pF与100nF电容组合,覆盖宽频率范围);
  • 无线AP:射频链路耦合,小封装适配高密度PCB布局。

五、可靠性与应用注意事项

1. 可靠性验证

该产品通过三环内部可靠性测试(如温度循环、湿热老化、焊接热冲击),符合IEC 60384-14(MLCC通用标准),平均无故障时间(MTBF)≥10⁶小时。

2. 应用注意事项

  • 电压降额:高温环境(>85℃)下,额定电压需降额至40V以下;
  • 焊接工艺:遵循三环推荐参数(回流焊峰值温度245±5℃,时间≤10s),避免手工焊接时温度过高;
  • 存储条件:常温干燥环境(温度<30℃,湿度<60%),存储时间不超过12个月,开封后尽快使用(避免端电极氧化)。

六、总结

TCC0201X7R471K500ZT是一款高性价比、小型化通用MLCC,以X7R介质实现宽温稳定性,0201封装适配高密度设计,50V电压覆盖多场景需求。适合消费电子、工业控制、通信等领域对容值密度、温度适应性有要求的电路设计,是替代进口同规格产品的可靠选择。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
